Question

The lengths of two sides of a triangle are 9 and 15. What can be said about the length of the third side?

Answer 1

(a) It must be greater than or equal to 6 and less than 24.
(b) It must be greater than or equal to 6 and at most 24.
(c) It must be greater than 6 and less than 24.
(d) It must be greater than 6 and at most 24.

Answer 2

let the third length of triangle is c, so to be a triangle it have to satisfies :
c+9 > 15
c > 15-9
c > 6
then, 9+15>c
in other words, c<9+15
so, c<24
now, find the match option :)

Answer 3

(c)?

Answer 4

a or c :p
